Sun glint correction methods of hyperspectral data that have been developed so far have not considered the various situations and are often adequate for only certain conditions. Also there is an inaccurate assumption that the signal in NIR wavelength is zero. Therefore, this study attempts to analyze the NIR spectral properties of sun glint effect in coastal waters. For the analysis, CASI-1500 airborne hyperspectral data, bathymetry data and in-situ data obtained at coastal area near Sin-Cheon, Jeju Island, South Korea were used. The spectral characteristics of radiance and reflectance at the five NIR wavelengths (744 nm, 758 nm, 772 nm, 786 nm, and 801 nm) are analyzed by using various statistics, spatial and spectral variation of sun-glinted area under conditions of the bottom types of benthos, barren rocks and sand with similar water depth. Through the quantitative analysis, we found that the relation of water depth or bottom type with sun glint is relatively less which is a similar result with the previous studies. However the sun glint are distributed similarly with the patterns of the direction of wave propagation. It is confirmed that the areas with changed direction of wave propagation were not affected by the sun glint. The spatial and spectral variations of radiance and reflectance are mainly caused by the effect of sun glint and waves. The radiance or reflectance of more sun-glinted areas are increased approximately 1.5 times and the standard deviations are also increased three times compared to the less sun glinted areas. Through this study, the further studies of sun glint correction method in coastal water using the patterns of wave propagation and diffraction will be placed.

본 연구의 주된 목적은 학교폭력 가해 경험이 있는 특성화 고등학교 학생들의 부모 양육태도가 학교폭력 가해 행동에 미치는 영향과, 자존감이 학교폭력 가해행동에 미치는 영향, 부모의 양육태도가 자존감에 미치는 영향 및 학생들의 학교폭력에 대한 인식을 분석하는데 있다. 연구대상은 총 122명으로 학교폭력 가해 경험이 있는 특성화 고등학교 남학생과 여 학생(남자 101명 여자 21명)이었다. 측정도구로는 부모양육태도와 배경정보에 대한 것은 Barber(1997)의 척도를 토대로 문항을 재구성하여 다시 제작한 김해영(2000)의 척도와, 자존감 측정도구로는 Rosenberg(1965)의 자존감 척도를 이춘진, 원호택 (1995)이 번안한 한국판 척도를 사용하였고, 학교폭력 가해 경험은 김준호, 김선애(2003)가 개발하고 김언지 (2004)가 수정 보완한 학교폭력 경험 측정도구 중 가해경험 문항을 사용하였으며, 학교폭력에 관한 인식은 김범수(2009)의 설문을 질적 문항으로 수정 보완하여 사용하였다. 분석 결과는 다음과 같다. 첫째, 부모의 양육태도가 학교폭력에 미치는 영향을 분석해 본 결과, 부모의 양육태도 중에 자율이 높아질수록 학교폭력은 낮아진다고 나타났다. 둘째, 부모의 양육태도가 자존감에 미치는 영향을 분석해 본 결과, 부모의 양육태도 중에 신뢰가 높아질수록 자존감이 높아진다고 나타났다. 셋째, 자존감이 학교폭력에 미치는 영향을 분석해 본 결과, 자존감은 학교폭력에 영향을 미치지 못하는 것으로 응답하였다. 넷째, 특성화 고등학교 학교폭력 가해 경험이 있는 학생들의 학교폭력에 대한 인식을 분석해 본 결과 학교폭력이 매우 심각하다고 가장 많이 응답하였으며, 보통, 미응답, 심각하다의 순으로 나타났다. 학교폭력의 주도적인 해결자로는 당사자가 가장 많은 응답을, 학교, 미응답, 경찰, 친구의 순으로 나타났다. The main purpose of this study is to analyze the impact of parenting behavior on school violence behavior of students of specialized high schools with experience in school violence, the impact of self-esteem on school violence behavior, the impact of parenting attitude on self-esteem, and the perception of school violence on students. A total of 122 students were subject to the study, with boys and girls from specialized high schools (101 men and 21 women) with experience in committing school violence. For measuring instruments, parents' adoptive attitudes and background information are based on Barber (1997), Kim Hae-young (2000) reconstructed and recreated based on Barber (1995), and Rosenberg (1965V s self-esteem measures were used by Lee Chun―jin and Won Ho―taek (1995),while Kim Sun-joon (1995) developed a Korean version of a school violence experience. The results of the analysis are as follows. First,after analyzing the impact of parental attitudes on school violence, it was found that the higher the self-esteem, the lower the school violence. Second, after analyzing the impact of parental attitudes on self-esteem, the higher the level of confidence among parents' attitudes, the higher the level of self-esteem. Third,after analyzing the impact of self-esteem on school violence, the results showed that self-esteem does not affect school violence. Fourth, after analyzing the perception of school violence by students with experience of committing school violence in specialized high schools,the school violence was most said to be very serious, in the order of normal,unresponsive and serious. As the leading solver of school violence, the parties responded the most,followed by schools,non-response, police and friends.

The recognition on leisure living which have been enjoyed by prestige level from popular persons is now widely spreaded in modern capitalism society and change of the leisure living influenced very much to the society and Industry. The 5 day work per week system expanded to the school and contemporary leisure living of the people is recognised as one culture with various contents. This change of leisure living made a recognition on the need for a space for leisure culture contents, which related to a creation of Complex-culture facility to contain various type of multiple leisure culture. The Complex-culture facility is mainly focused on the entertainment space with increased leisure living, which is consist of important element of the Complex-culture facility as performance space, exhibition, sports and shopping space to construct performance hall, theater, exhibition room, sports center, shopping mall, leisure space and plaza. This study, therefore, will Investigate on the function and value of color, and review on the cases of Complex-cultural facility and then choose a space of cultural element lack. It will recompose in Complex-cultural facility.

Increase of national family income improved demand of high-quality and year-round horticultural products including chrysanthemum. To meet these demand, farmers have introduced protected facilities, such as greenhouses, of which environmental conditions could be monitored and controlled. Environment management up to three weeks after transplanting is critical for chrysanthemum quality. Artificial lighting and light-blocking screen are especially important for long-day (day period > 13 hours) and short-day (night period > 13 hours) treatments. In this study, a web-camera was installed, and the image was obtained and transmitted to mobile phones to monitor the status of 3-wavelength(RGB) lighting environments. RGB pixel values were used to determine malfunctioning of the lighting lamps, and leaking out and incoming illumination status during short-day and long-day treatment periods. Normal lighting lamps provided RGB pixel values of 240~255. During long-day treatment period, G pixel values were useful to detect abnormal lighting conditions (e.g., leaking). During short-day treatment period, R pixel values were useful to determine incoming light (e.g., sun-light). Results of this study would provide useful information for remote monitoring of light conditions for protected chrysanthemum production under artificial lights.

In this study, we manufactured ATO (antimony tin oxide) combined fibers to improve solar energy transmittance of sunscreen fabrics. The results indicate that the solar energy transmittance is improved with increasing sheath ratios and ATO content. We observed that the MS2-7W sample with 50:50 sheath/core ratio and 3 wt% of ATO content show the best performance. We also manufactured the sunscreen fabrics using the developed ATO combined fibers to check the performance of the thermal barrier. The results of the solar energy transmittance analysis show that an approximate 58% improvement was achieved for the thermal barrier over the commercial sunscreen fabric without any ATO content.

If we embank on the soft ground, to construct road and other structures, Settlement and lateral displacement in the subground develop during and after the construction of embankment. Because lateral displacement and settlement in the ground can affect close structure and piles and used as important measure data indeciding safety of the embankment frame, it is important precisely to forecast the size and distribution of lateral displacement and settlement. Therefore, in this study, to analyze lateral displacement according to construction and ground condition, practiced two dimentional finite element analysis using the finite element analysis program SAGE CRISP 4.02. Embankment condition is the change of embankment decline and velocity, Ground condition is the change of drainage condition, OCR and permeability coefficient and the mixture of over consolidation layer and sand layer in the ground. As a result of analysis, whole lateral displacement increase inconstant velocity before embankment completion and after embankment completion, lateral displacement velocity decrease and is very small in 1000days. Besides, maximun lateral displacement in the embankment frame hem is restrained according as hardness of the ground is large and drainage well occurs.
